It has been over ten years since I played Skies of Arcadia but I have only good memories of this game.
I remember that the dungeons and the battles were very repetitive but on the other hand the mechanics of the naval battles and the recruitment of the crew were really innovative and fun.
Vyse, Aika and Fina are good characters, but not particularly deep for what I remember, for me the highlights of the game were the worldbulding and the setting.
This is a game that SEGA has forgotten and that I would like to play on my Nintendo Switch.
